A growing construction industry and rising home sales are among the signs that an economic rebound is underway after a weak first quarter. The Federal Reserve is likely to raise interest rates if that keeps up.

Wall Street has gone from worrying the economy is not strong enough to thinking it might be too strong.

Neither feast nor famine, of course, are apt images of how the U.S. is performing. The economy is muddling along just like it’s done for the past seven years.

Still, any further signs of economic vitality are sure to prompt the Federal Reserve to raise interest rates, perhaps as early as June. Minutes of the Fed’s meeting in April appeared to show surprising agreement on the need to take action.

And that has rattled financial markets — again. Stocks tumbled last Thursday on fears on an impending increase — higher interest rates hurt stock prices. Equities recovered to end the week on the conviction the Fed’s not quite ready to pull the trigger, but investors are clearly on edge.

A batch of economic reports this week is likely to push the Fed closer to its second increase in U.S. interest rates — the cost of borrowing — since December. Not because the vital signs of the economy are expected to be strong, mind you. They simply aren’t going to show much weakness.

New home sales and an index of pending home sales, for example, are forecast to rise in April. Sales to first-time buyers have been on the rise, a sign that younger people are increasingly able to afford a home and feel confident enough about the economy to do so.

Orders for durable goods might fall a touch in April, but they’ve been weak for months. So long as there’s no big dropoff, the thinking inside the Fed is unlikely to be swayed.

A second look at gross domestic product in the first quarter, meanwhile, will probably show the economy was not quite as weak as preliminary figures suggested. GDP growth is likely to be revised up to 0.9% from 0.5% in the first three months of the year. Slow growth in early 2016 briefly spawned talk of recession.

At the same time, the Fed’s long desired increase in an ultra-low U.S. inflation rate appears on the way. Consumer prices rose in April at the fastest pace in two years.

Oil prices, though still cheap, have risen sharply in 2016 and a muscular dollar has finally lost a little strength after an extended runup. The greenback has dropped 5% in value since hitting a 14-year high early in the year. That will push up the cost of U.S. imports but also help U.S. exporters.

“The two deflationary shocks of 2015 — the surge in the dollar and the slump in commodity prices — are fading rapidly,” Capital Economics wrote in its weekly survey of the economy.

The Fed still has to tread very carefully, though. Higher interest rates are likely to dent home sales, one of the economy’s pillars of strength in the past few years. And if the Fed moves too fast the dollar is likely to surge again and tighten a chokehold on export-heavy American manufacturers.

“Manufacturing has been a clear drag on the U.S. expansion over the past year,” said Scott Anderson, chief economist of Bank of the West. He doesn’t expect a significant improvement until next year.
